Parasitic myomas after laparoscopic surgery: an emerging complication in the use of morcellator? Description of four cases

ObjectiveTo report the development of parasitic myomas after the use of a morcellator.DesignRetrospective study.SettingTertiary care referral center for the treatment of benign gynecologic pathologies.Patient(s)Women undergoing surgery for uterine fibroids.Intervention(s)Chart review.Main Outcome Measure(s)Presence of parasitic leiomyomas.Result(s)We identified four cases of parasitic myomas over the 3-year study period. Two out of the four were symptomatic. The prevalence of this complication, considering all women with whom the electric morcellator was used (n = 423) was 0.9% (95% CI, 0.3-2.2%). Considering exclusively the women who underwent myomectomy (n = 321), it was 1.2% (95% CI, 0.4-2.9%).Conclusion(s)Laparoscopic myomectomy with the use of a morcellator is associated with an increased risk of developing of parasitic myomas. A thorough inspection and washing of the abdominopelvic cavity at the end of the surgery should be performed to prevent this rare complication.
